Special-shaped steel pipe column reinforced concrete ring beam construction method

Abstract

The invention provides a special-shaped steel pipe column reinforced concrete ring beam construction method and belongs to the technical field of building construction. The construction method comprises the steps that a steel pipe concrete column is connected with a reinforced concrete beam; a beam-column joint processing method of an annular bracket is adopted by joint processing; a corresponding steel bracket is additionally arranged during machining of the steel pipe column, specifically, the steel bracket is formed by welding a steel plate which is 22 mm thick; a ring beam and a frame beam are bound to the steel bracket; main steel bars of the beam are anchored into main steel bars of the inner side of the ring beam; and concrete of the frame beam and a slab are poured. Due to the facts that the steel bracket is located in the middle of the ring beam, and the main steel bars of the lower row of the ring beam are located on the inner side of the steel bracket, ring beam steel bars cannot be bound on a machining site and then suspended like a conventional ring beam, and an on-site binding construction mode is adopted. Through practice examination of the method in engineering, the installation problem of ring beam joint steel bars is solved; and according to the method, safety is guaranteed, the construction quality is good, the speed is high, the comprehensive construction cost is low, and the economic benefits and social benefits are remarkable.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for a special-shaped steel pipe column reinforced concrete ring beam. Background technique [0002] In general, as a composite structure that can make full use of the characteristics of steel and concrete materials, the steel tube concrete column has been widely used in engineering, which improves the technical rationality and economic superiority. However, as an important beam-column joint in CFST columns, it has evolved from the relatively single connection between steel beams and CFST columns or the connection between reinforced concrete beams and CFST columns in the past to a CFST column joint that has both reinforced concrete beam connections and rings. Beam connection, its stress and structure are complex. Contents of the invention [0003] The technical task of the present invention is to solve the deficiencies of the prior art and...
